Ironclad

Backed by his "Magnificent Seven," a principled Knight Templar (James Purefoy) defends Rochester Castle from the ruthless King John (Paul Giamatti) and his advancing armies, who seek to rule England's free men by force -- no matter what the Magna Carta might say. Charles Dance, Kate Mara, Jason Flemyng, Brian Cox and Derek Jacobi co-star in this action-packed period piece set at the height of the Middle Ages.
